Title: Method and apparatus for the treatment of fluid
IPC: B01J47/10
Filed: 1970-09-04
Abstract: 1327058 Valves FILTRES VERNAY SA 4 Sept 1970 [9 Sept 1969] 42347/70 Heading F2V [Also in Divisions B1 and C1] A panel of sheet material has a number of perforations therethrough to allow fluid flow, the perforations being formed as unidirectional or check valves to allow fluid flow in one direction only through the sheet. In Fig. 7 the sheet material is flexible, e.g. rubber or plastics, and the perforations are in the form of cruciform slits providing supple lips 28 which will separate to allow fluid flow therethrough. A fine-mesh grill 25 is applied to the intended upstream side of the sheet. This prevents the lips 28 opening in that direction. In Fig. 10 the flexible sheet 26 has perforations each formed with tongues 28 having claws 29 formed at their ends. These claws close upon one another if the fluid flow is in the direction 30, but open out if it is in the opposite direction. In Fig. 19 the sheet material is formed by helically coiling a profiled band of flexible material, e.g. rubber or plastics, on to a mesh or other rigid frame 54. The band comprises a heel 56 extending along one edge and a thin flexible lip 57 along the opposite edge. The coiling of the band is carried out with a slight overlap so that lip overlaps heel. This will not allow fluid flow in direction 58 but only in the opposite direction.

Title: The method of and apparatus for producing regenerated cellulose filaments by wet spinning viscose and recovering the gases generated during the spinning operation
IPC: D01F13/02
Filed: 1959-12-14
Abstract: <PICT:0925741/IV(a)/1> The gases evolved during the production of viscose rayon are recovered undiluted by air by extruding bundles of filaments upwards from a row of spinning nozzles 3 (Fig. 1) situated in a spinning bath 2, each bundle of filaments being drawn into and through a vertical tube 4 situated above the corresponding spinning nozzle and forming one of the inlet limbs of a syphon. The lower end of each tube 4 dips into the spinning bath 2 and the upper end of each vertical tube 4 opens into the substantially horizonal portion 1 of the syphon into which the bundles of filaments are drawn to form a tow of increasing cross-section as the tow travels towards the outlet or discharge limb of the syphon.  The tow is drawn from the portion 1 of the syphon into and through the vertical discharge limb of the syphon, the lower end of which limb dips into a body of spinning bath liquid located at a lower level than the spinning bath 2 and contained in a tank 5, the syphon outlet being thereby hydraulically sealed.  The tow is withdrawn from the discharge limb of the syphon round the guide 12 and out of the liquid in the tank 5 by means of the squeeze rolls 7.  The spinning bath liquid flows through the syphon at a linear velocity lower than that of the tow into the tank 5 which is covered by a hood 5a the side walls of which dip into the spinning bath liquid in the tank 5 so that the gas space under the hood is hydraulically sealed, the gas being discharged from the hood by the pipe 10 the outlet end of which is also hydraulically sealed. The lower or inlet end of each vertical tube 4 is provided with a funnel-shaped enlargement.  The horizontal portion 1 of the syphon and also the curved portion thereof are provided with transverse ribs 12 which serve as stationary guides for the individual fibre bundles drawn from the top of each tube 4 and for the tow of increasing size formed by the assembling of these bundles.  The ribs 12 also cause the flow of liquid through the syphon to be turbulent.

IPC: C08G77/58
Filed: 1960-12-13
Abstract: Metalloxane-siloxane polymers, containing units having at least one alkoxy group bonded to a metal atom and represented by the formula <FORM:0991284/C3/1> where R is an alkyl group, R1 and R11 are monovalent hydrocarbon groups, M is Al, Ti or Zn, and n is the valency of the metal atom in the polymer less 2, are phosphonated by reaction with a mono- or di-alkyl phosphonic acid or a mono- or di-aryl phosphonic acid.  The reaction can be effected by heating the reactants under reflux conditions with stirring, preferably in an inert atmosphere and, if desired, in an inert reaction medium, e.g. butyl acetate.  In Example (1) diphenyldiacetoxysilane was reacted with aluminium isopropoxide to yield a resin which was mixed with diphenyl-phosphonic acid with subsequent heating and stirring under a cover of dry nitrogen; volatiles were distilled off and low molecular weight polymers and unreacted material were extracted with ethanol to leave the desired product as a white powder. Similar preparations of the corresponding Ti and Zn products are described in Examples 2 and 3, respectively.

Title: Method and a device for the degassing and thermal treatment of  sensitive liquids in particular of milk products
IPC: A23L3/18
Filed: 1972-09-15
Abstract: 1367213 Thermal treatment of liquids WIEGAND KARLSRUHE GmbH 15 Sept 1972 [23 Sept 1971] 42922/72 Heading A2D A method for the degassing and thermal treatment of a liquid, particularly milk, comprises first heating the liquid in a lower temperature range by contact with a heat-supplying surface, then heating to a higher temperature range in at least one heating stage by the introduction of vapour of said liquid from a subsequent cooling stage, further heating to a maximum temperature by the introduction of pressurised steam, the liquid then being cooled by expansion, the vapour so produced in the cooling step being introduced into the at least one heating stage. The lower temperature range preferably has an upper limit of 40‹C. After the high-level heating, the liquid is preferably cooled in at least three decompression stages and is homogenised before the third temperature drop, which is down to 40‹C. The method may be carried out in the apparatus shown in the accompanying figure, wherein liquid to be treated is intially pumped through a succession of surface heaters 2, 3 and 4. Heaters 2 and 4 utilise the heat from vapours 5, recycled through lines 24 and 18 respectively, wheras heater 3 utilises steam. The preheated liquid is then passed to mixed preheaters 8 and 10 for further heating by direct contact with vapours recycled via lines 15 and 17. The liquid then passes to a high temperature heater 12 which uses steam as a heating medium. From heater 12, the liquid is passed to a series of decompression chambers 14, 16 and 21. The liquid is cooled in these chambers, and the vapours evolved during the decompression steps are recycled as previously indicated. A homogeniser 20 is positioned between decompression chambers 16 and 21. A condenser 23 condenses the portion of the vapours from chamber 21 that will not be recycled to preheater 2.

Abstract: 1364080 Digital processors PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 20 Sept 1971 [23 Sept 1970] 43716/71 Heading G4A A data processing system includes a central processor CPU having a command register CR and a store WS, a number of control units CU1, CU2 and a number of peripherals P1, P21, P22 which may be at differing distances from the CPU and have differing operating speeds. The system includes a counting arrangement for ensuring that an input-output data transfer procedure can continue provided an affirmative answer indicating readiness is received from a control unit within a preset integral number of store cycles from the time of transmission of an interrogation signal. If an input-output procedure is to be performed via control unit CU2 an interrogation signal is sent to CU2 on line 13. This signal also passes via OR gate 1 to AND gate 3 and to differentiator 5. The output of differentiator 5 sets binary counter C to full count, the counter now being stepped down by pulses on 15, each such pulse occurring after an integral number of store cycles. When an affirmative reply is received from the unit CU2 via line l4 OR gate 2 provides a signal which inhibits gate 3 so preventing further stepping of the counter C. On the other hand if the affirmative is not received before counter C is stepped to zero, gate 4 detects the zero state and stops the input-output procedure by a signal on line l6.
